SPECIFICATION forming part of Letters Patent No. 285,624, datedSeptember 25, 1883,

Application filed May 14, 1883; (No model.) I

To aZZ whom it may concern..-

Be it known that I, WILLIAM LANE HUT- soN, a citizen of the UnitedStates, residing at brake mechanism in connection with the rear portionof a running-gear. Fig. 2 is a'side view, showing the levers thrownforward for applying the brake. Fig. 4 is a side view of the levers,illustrating the operation of releasing the brake.

The brake-beam A is suspended from the rear hounds, B, so as to swingfree beneath them, and when moved backward applies the blocks a to therear wheels, 0.

The means for moving the brake-bar consist of two levers, .D E, whichare bent at a right angle, their horizontal portions being journaledside by side in arms d, attached to the rear axle, F. The inner end ofthe front lever, E, is bent forward at a right angle, and

. is connected-with the brake-beam by means of a rod, 2), and metalplate a, that enters a slot in the brake-beam. Theplate is provided withholes to receive a pin or bolt, (1, that 7 passes vertically through thebrake-beam and is held in place by a cap-plate, e, as shown in Fig. 3.By adjusting plate 0 in the slot of the brake-beam A the wear of theblocks a may be compensated for, so that the brake may to the otherlever. A ratchet or toothed pawl, F, is pivoted to the upper end oflever E, and extends backward over a catch-plate, g, fixed on the axleG. The front end of said pawl F is turned upward to adapt it to engagewith a trip-dog, H, which is pivoted to the longer lever D.

The lever D may be operated by hand; but in this instance I employ acord, I, which is attached to its upper end,, as shown, and in practiceextends forward to the drivers seat.

The operation of my improved brake mechanism is as follows: In thenormal position the vertical arms of levers D E are inclined backward,as shown. in Fig. 1. When the cord -I is pulled, the vertical arms ofthe levers are both carried forward, since the upper end of rock-lever Ebears against lever D, and is hence compelled to move with it. In thismovement the inner bent end of lever E is thrown down, which obviouslyhas the effect of drawing. the brake-beam A backward and applying thebrake-blocks to the wheels. The ratchet-pawl F also comes into action atthe same time, and by engagement with the catchplate 9 holds therock-lever E in the position to which it has been moved forward, andthus keeps the brake applied. On releasing the cordI the spring f throwslever D back, as shown in dotted lines, Fig. 2. Said lever then resumesthe position shown in Fig. 1. When it is desired to release the brake, asecond pull on the cord I carries the lever D forward again, and thistime its dog H comes in contact with the upturned end of theratchet-pawl F, Fig. 4, and trips the latter, thus allowing the spring fto throw the lever E back to its normal position and allowing thebrake-beam Ato swing free, as before. As the rock-lever E is thrown backthe trip-dog H slips over the end of the ratchet-pawl F and resumes its0 former or normal position. It will be perceived, therefore, that thefirst forward movement of the lever D applies the brake, and that thelever resumes its normal position as soon as the cord is released, andthat on the 5 second forward movement of lever D the brake is let off.

The mechanism for operating the brake-bar may be attached to the rearaXle alone, or partly to it and the side of the wagon-body, as foundmost convenient and practicable.

What I claim is 1. The combination, with a brakebean1, of two levers, aholding-pawl, and a trip device, substantially as shown and described,to opcrate as specified.

2. The combination, with the brake-beam, of the rock-lever E and aratchet-pawl pivoted thereto, and the main operating-lever D, hav= ing atrip-dog attached, and arranged for acting on the upturned end of thesaid pawl, all substantially as shown and described.

3. The combination, with the brake-beam, 15

the second lever is moved forward, as shown 20 and described.
